Montage of planets and some moons that the two Voyager spacecraft have visited and studied. It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.
Voyager 2 flew by Uranus and was the first spacecraft to visit it. Neptune 25 August 1989 4389 days (12 yr, 6 days) Voyager 2 flew by Neptune and was the first spacecraft to visit it. Voyager 1: Jupiter 5 September 1977 5 March 1979 547 days (1 yr, 6 mo, 1 d) Voyager 1 flew by Jupiter and returned the first detailed images. [94] Saturn 12 ...
These probes make Jupiter the most visited of the Solar System's outer planets as all missions to the outer Solar System have used Jupiter flybys. On 5 July 2016, spacecraft Juno arrived and entered the planet's orbit—the second craft ever to do so. Sending a craft to Jupiter is difficult, mostly due to large fuel requirements and the effects ...
The spacecrafts were then moved into a separate program named Mariner Jupiter-Saturn (also Mariner Jupiter-Saturn-Uranus, [19] MJS, or MJSU), part of the Mariner program, later renamed because it was thought that the design of the two space probes had progressed sufficiently beyond that of the Mariner family to merit a separate name.
The spacecraft would be designed with redundant systems to ensure survival throughout the entire tour. By 1972 the mission was scaled back and replaced with two Mariner program-derived spacecraft, the Mariner Jupiter-Saturn probes. To keep apparent lifetime program costs low, the mission would include only flybys of Jupiter and Saturn, but keep ...
It arrived at Jupiter on December 7, 1995, via gravitational assist flybys of Venus and Earth. [40] Despite antenna problems, Galileo conducted the first asteroid flyby, discovered the first asteroid moon, was the first spacecraft to orbit Jupiter, and launched the first probe into Jupiter's atmosphere. Galileo's prime mission was a two-year ...
Montage of planets and some moons that the two Voyager spacecraft have visited and studied, still active in the 2020s they are heading out into interstellar space returning data from newly explored distances. Europa Clipper. Mission: mission to study Jupiter and Europa. Launched: 14 October 2024; Destination: Jupiter; Arrival: 11 April 2030 (en ...
The spacecraft generated an infrared map of the planet, which confirmed the idea that the planet radiated more heat than it received from the Sun. [51] Crescent images of the planet were then returned as Pioneer 10 moved away from the planet. [52] As the spacecraft headed outward, it again passed the bow shock of Jupiter's magnetosphere.
